OSHA: The legal airborne permissible exposure limit (PEL) is 3 0.1 mg/m averaged over an 8-hour workshift. Skin Contact f Quickly remove contaminated clothing. Immediately wash NIOSH: The recommended airborne exposure limit (REL) is contaminated skin with large amounts of soap and water. 3 Seek medical attention immediately. 0.05 mg/m (as Mercury vapor) averaged over a 10-hour workshift and 0.1 mg/m3 (as Mercury), not to
